Description

Waterproff keyboard

Technical field

The present invention refers to especially that relevant for a kind of keyboard a kind of liquid that prevents seeps water to the waterproff keyboard of motherboard.

Background technology

General notebook computer 10 mainly comprises modules such as screen 20, keyboard 30 and pedestal 40 as shown in Figure 1, and wherein: aforementioned screen 20 and pedestal 40 are to link one by hinge means; Aforementioned keyboard 30 is arranged on the aforementioned pedestal 40; Aforementioned pedestal 40 inside are holding the motherboard that surface mount has electronic components such as CPU, and this motherboard is positioned at the below of aforementioned keyboard 30.

Aforementioned keyboard 30 is that recombinant is to aforementioned pedestal 40 after being assembled into as shown in Figures 2 and 3 module (the relevant distribution of graphic omission) by plural button 31, the chassis 35 with flange 37 and rubber body layer 33 described later and board layer 34.

The main composition of aforementioned keyboard 30, it is as follows to cooperate Fig. 4 to Fig. 8 to further specify.

The sealant 38 that Fig. 4 demonstrates keyboard 30 separates (promptly not sticking together as yet) in the state on the chassis 35 of carrying button 31, and wherein the shape of sealant 38 is the shape corresponding to chassis 35 haply, and sealing layer 38 is that the soft or hard material of plastics all can.Please continue referring to Fig. 5, a plurality of holes 36 that for example form that distributing, the chassis 35 that this Fig. 5 demonstrates Fig. 4 with impact style, and also form snapping, the fixing required lug (scheming not show) of aftermentioned rubber body layer 33 and board layer 34 during punching press in the lump.According to earlier figures 4 and chassis 35 and sealant 38 shown in Figure 5, be by at chassis 35 lower surface surrounding edges or on sealant 38 surrounding edges, smear gum 39, make sealant 38 be attached to chassis 35 lower surfaces, please referring to Fig. 6.Stick together the keyboard 30 that sealant 38 is arranged, need through the baking program viscose to be solidified with complete combination seal layer 38 and chassis 35, the keyboard 30 after the baking promptly constitutes module as shown in Figure 2.Profile via Fig. 7 and Fig. 8 shows, can understand fully that keyboard 30 mainly comprises button 31, rubber body layer 33, board layer 34, chassis 35 and the sealant 38 of from top to bottom configuration.Formation because of aforementioned keyboard 30 belongs to known technology, does not repeat them here its thin bilge construction.

Notebook computer 10 (please refer to Fig. 1) has compact property easy to carry, acquisition expenses thereby than desktop PC height.When preventing this computer of user's Operational Note, accidentally liquid such as beverage are knocked over and sprinkle the notebook computer that damages costliness into keyboard 30, known keyboard 30 be provided with aforementioned sealant 38 in the chassis 35 lower surface, make keyboard 30 constitute a water proof type keyboard, its purpose promptly by the hole 36 on sealant 38 sealing chassis 35 with impermeability with stop sprinkle into liquid, liquid is stayed on the chassis 35 and can not flow to the motherboard of below by the hole 36 on chassis 35, to guarantee the motherboard damage of can not soaking, keep the operability of notebook computer.

Aforementioned chassis 35 of carrying button 31 must be made with hard, strong material especially because of the active force that is subjected to the user to operate pressing keys 31, and metal for example is to prevent keyboard 30 flexural deformations; And the material that sealant 38 is selected for use must be fluid-tight thin slice material especially, to avoid increasing integral thickness.

Yet, between sealant 38 and chassis 35 lower surfaces is to stick together in the gum mode to combine, sealant 38 or chassis 35 are for having at least for example size of 10cm * 27cm, through the baking program, the buckling phenomenon that promptly produces rising-heat contracting-cold as shown in Figure 9 because of the coefficient of expansion of 35 liang of materials of sealant 38 and chassis is different (promptly, be different from the shown normal due level levelling state of Fig. 7), make the two ends of keyboard 30 tilt upward and produce a difference in height D with horizontal line 32 that chassis 35 should be the level of state, and sealant 38 can't be combined closely with chassis 35, and the generation slit, in the time of in too much liquid sprinkles into keyboard 30, liquid will be stranded in the slit on 35 on sealant 38 and chassis, and can't discharge, or along sealant 38 and chassis 35 the slit and flow to the motherboard of keyboard 30 belows, cause the motherboard immersion to damage, can't operate.

Therefore how to solve the chassis and cause the different buckling phenomenons that produce of two material thermal coefficient of expansions because of sticking together combination through the baking program with sealant two different materials, and then sealant can't be combined closely with the chassis, sprinkle into keyboard to prevent that liquid from knocking over accidentally, and make the motherboard of flow of liquid to keyboard below, cause the motherboard immersion to damage, can't operate, real industry problem demanding prompt solution for this reason.

Summary of the invention
